Burn slightly in housing estate (5)
I believe the answer is:
singe
'burn slightly' is the definition.
(I've seen this before)
'in housing estate' is the wordplay.
'in' indicates a hidden word.
'SINGE' is hidden in the letters of 'housing estate'.
(Other definitions for singe that I've seen before include "Scorch lightly" , "Burn the ends or edges of" , "Char, scorch" , "slight burn" , "Sear" .)
